ONE-PACK PREPARATION FOR DISINFECTION, NEUTRALIZATION AND CLEANING OF CONTACT LENSES AND METHOD OF DISINFECTION, NEUTRALIZATION AND CLEANING

摘要

PURPOSE: A preparation for simultaneously conducting disinfection, neutralization and cleaning of soft contact lenses, and a method for using easily, efficiently, and safely the preparation are provide. CONSTITUTION: The preparation comprises a combination of a first preparation containing an iodine disinfectant and a protease with a second preparation containing a reducing agent and a foaming agent and having a coating for delayed release, and a nonionic surfactant is contained in at least one of the first and second preparations. Soiled soft contact lenses are kept in an aqueous solution yellowed or browned with iodine molecules, and, after the aqueous solution has become substantially colorless, the lenses are separated from the aqueous solution, thus facilitating a series of procedures, that is, disinfection, neutralization, and cleaning.
